Abstract
The invention comprises esters of metaboric acid of the formula <FORM:0815140/IV (b)/1> in which R is an alkyl radical containing 2 or more carbon atoms, preferably 2 to 12 carbon atoms. The novel compounds may be prepared from a dialkyl chloroboronate by heating, preferably at from 150 DEG to 250 DEG C. for 2 to 10 hours and at superatmospheric pressure if required, or by addition of a Lewis acid catalyst, such as ferric chloride or aluminium chloride, preferably in an amount of 0.1 to 10 per cent by weight based on the dialkyl chloroboronate. The esters of metaboric acid may also be prepared by heating an alkyl orthoborate with boron trioxide, preferably in the molar ratio 1 : 1 or with a slight excess of boron trioxide. The heating is suitably effected at a temperature greater than 100 DEG C., preferably in the range 150 DEG to 250 DEG C., and the reaction may be effected at superatmospheric pressure. In examples: (1) ethyl orthoborate and boron trioxide are heated at 250 DEG C. for 10 hours in a sealed glass tube to give ethyl metaborate; (2) diethyl chloroboronate is heated at 250 DEG C. for 10 hours in a sealed tube to give ethyl metaborate; (3) isopropyl orthoborate and boron trioxide are heated for 3 hours under reflux to give iso-propyl metaborate; (4) iso-propyl metaborate is obtained by heating di-iso-propyl chloroboronate at 200 DEG C. for 5 hours; (5) n-propyl metaborate is obtained from n-propyl orthoborate and boron trioxide as in (3); (6) n-propyl metaborate is obtained from di-n-propyl chloroboronate by the procedure of (2); (7) n-butyl orthoborate and boron trioxide are heated at 240 DEG C. for 8 hours to give n-butyl metaborate; (8) n-butyl metaborate is obtained from di-n-butyl chloroboronate by the procedure of (2); (9) di-n-butyl chloroboronate is treated with anhydrous ferric chloride to give n-butyl metaborate; (10) iso-butyl metaborate is obtained from isobutyl orthoborate and boron trioxide by the procedure of (7); (11) isobutyl metaborate is obtained from di-isobutyl chloroboronate by the procedure of (2); (12) sec-butyl metaborate is obtained from sec-butyl orthoborate and boron trioxide as in (7); (13) sec-butyl metaborate is obtained from di-sec-butyl chloroboronate and aluminium chloride by the procedure of (9).
